To all whom, it may concern.- B a pipebox having at the inner end a Be it known that I, JOHN F. PACKER, reflange, B', ot larger diameter than the box, siding at Chicago, in the county of Cook and and having asquareinner faeeto form ashont State of Illinois` and a citizen of the United der, b, and the interior of this iin-nge at the 55 5 States, have invented a new and useful Imend has an opening, B, to receive the end of provement in' Hubs and Vheels, of which the the axle, and have the shell of the flange form following is a full description, refereneebeing a sand-box.

The pipe-box is next inserted, so that the shoulder b will abut against the end of the hubsections, and the screw-nut C is applied to the end of the pipe-box, bringing the shoulder c in Contact With the other end of the hub, holding the hub firmly between the shoulders b c, so that the ratchet-teeth will be held against accidental displacement, and the hub as a whole will be held from swinging apart. The wheel is now ready for use, and can be applied to the axle in any usual and well-known manner. As shown, the nut C is designed for use in connection with an axle-nut5 but it could be used with a linchpin or other fastening device.

Figs. 8 to l2, inclusive, showa construction of hub designed for use without a pipe-box, and Figs. 18 and 14E show a complete wheel, constructed with this forni of hub.

rEhe construction of the hub is essentially the same as that already described, consisting of two sections or halves, A, having at theirl outer end iianges A, with openings a for the passage ofthe spokes, and having their' inner ends provided with ratchet-teeth. rlhe outer end of cach sectionhas a central elongated part, A, which projects beyond the'iianges A and i'ornis the ends proper of the hub in the forni of construction shown; and one section of the hub at the inner end has an elongated portion, A", which enters a recess formed in the other section, so as to give the hub a central bearing longitudinally around the ratchet-teeth, to prevent displacement when the hub is turned to produce the proper strain on the spoke for the required tension in use. The holes a', instead of passing transversely through the flange A, as in the other form of construction, are formed by cutting a recess on the inner face of the Harige A; but the i spokes D are passed through the opening in the manner before described, so as to have a portion, d, on the interior of the flange extending from hole to hole, through which the spoke is passed, as shown in Fig. 1l.

rlhe strain is put upon the wheel in the same manner as before described by turning the hub-sections against each other, and, if desired to facilitate the turning, the ii'ange b', in either form of construction, may be formed six or eight sided or otherwise, to receive a wrench having a corresponding shape.

The tendency of the strain on the spokes of the hub-sections is to draw them inward, insuring a firm interlocking of the ratchet ends, and this strain is sufficient to hold the hubsections together under ordinary circumstances, and any spreading will be prevented when the hub is in place by the contact of the ends with the axleshoulder and the locking-nut or liuchpin.

The preferred form is that in which the sections are made of equal length to bring the engaging teeth in line with the center of the rim or tire, so that the strain of the spokes will be at the same distance from the center of the hub in all directions, whereby extra draw at any one point is prevented. This same construction can be used with the form of hub shown in Fig. l0, and is preferred.

I do not claim, broadly, a hub made in two rotatable parts, nor a two-part hub provided with ratchet-teeth on the meeting parts of the hub.

Vhat I claim as new, and desire to secure by Letters Patent, is-

l. A hub consisting of sections of equal length, each having its inner end provided with ratchet or engaging teeth, and its outer end with spoke-openings for bringing the strain equally over the length of the hub and preventing extra draw at any one point, substantially as and for the purposes specified.

2. A hub formed of sections A of equal length, having ratchet-teethaand end ianges, A', provided with openings a, in combination with spokes D and rim E, whereby the strain is brought equally over the length of the hub and eXtra draw at any one point prevented, substantially as and for the purpose specified.

3. The combination, with a hub formed of sections A of equal length, having ratchet or engaging teeth a, whereby the strain is brought equally over the length of the hub and extra draw at any one point is prevented, of a pipe-box, B, having a iiange, B', and a locking-nut, O, substantially as and for the purposes speciiied.
